SEALED room w/ portable a/c do I vent?

[budcollector]

My sealed room is small but I still need a portable ac to deal with the sealed room temp of 2x600w + 320w in the mother room.

There seems to be an exhaust on the portable a/c - I am assuming this is to vent outside the room - since its very hot air.

I found a Danby that has an vent in and vent out - dual exhuast.

What do I do - does venting the ac break the seal? I would think so.

Any help to clarify this before I spend the cash.

you only vent the exhaust outside the room. Just run the pipe through the wall with a dryer vent pipe.

does that create a negative pressure in the room?

and am I losing CO2 because of this?

No the air the AC unit cools is room air. The heat is a by product from the compressor & the cooling process and not from the room.
